FIELD OF THE INVENTION

The present invention relates to an electric fireplace, more particularly, a stereo flexible charcoal bed and an electric fireplace with a stereo flexible charcoal bed.

BACKGROUND OF THE INVENTION

The simulative charcoal bed of the conventional electric fireplace is of integral strip structure made of translucent material. The charcoal bed is disposed at the back of and below the image screen of the electric fireplace, and a charcoal flame image is formed on the image screen after the projection of imaging light source. The structure described above leads to dull appearance of the charcoal flame and bad visual effect. Moreover, the color of the charcoal flame is achieved by coloring the simulative charcoal bed and the image screen. The color and brightness of the charcoal flame is very monotonous and lack of variety. To solve the shortcomings described above, an independent light source for the simulative charcoal bed is adopted. Such as the artificial wood for electric fireplace disclosed in the patent with publication date Apr. 7 2004 and publication number CN 2610233, comprises an artificial wood base and a light source. The base is an irregular transparent chamber with artificial wood figure. LED or light bulbs are disposed in the chamber. Each LED tubes or light bulbs are connected in series or in parallel and then lead out of the base by a conducting wire to connect with an external power source. The artificial wood base is of translucent material with pigment layers disposed irregularly on the external surface. The pigment layers can be chosen from various colors according to simulation needs, ordinarily, the dark brown similar to the wood color. The patent described above combines the artificial wood base and the light source. The light source is disposed in the artificial wood base. The base with pigment layer irregularly smeared on the external surface is made of transparent material. Thus, when the light source inside generates light, a kind of artificial burning effect with light and shade stager with each other is achieved, which is similar to the effect of burning charcoals. The structure is simple, realistic, and independent light source is disposed inside every simulative wood which means one could arrange and stack the wood arbitrarily. The figure and realism is closely to the natural burning flame. Such as the electric fireplace with LED light source disclosed in the patent with publication date Apr. 14 2008 and publication number CN 201050823, comprises a electric fireplace housing, a image screen with a central portion disposed vertically, simulative charcoals disposed in front of the image screen, a reflective axis disposed at the back of the image screen to reflect light to the image screen, a plurality of LED disposed in the simulative charcoal, a plurality of LED projecting light to the reflective axis disposed below the reflective axis. The LED with various colors disposed inside the simulative charcoals acts as a light source of the simulative effect to get multi-layers of simulative colors in variation. The LED projecting light to the reflective axis disposed below the reflective axis acts as the light source of simulative flame, all of the light projects to the reflective axis. The reflective axis reflects the light to the image screen and a flame image is simulated on the image screen. The shift between light and shade of the LED as reflecting light source makes a sparkling effect of the electric fireplace simulative flame with more reality. The structures described above improves the light source of the charcoal bed, but the simulative charcoal bed itself is still of an integrally translucent structure. The integral structure of charcoal bed influences the transmission of light, and the translucent structure influences the brightness of flame, so the improvement of these kinds can not reach to an ideal visual effect. The charcoal flame simulated through the structures like the fixed wood or charcoal bed structure changes the color brightness mainly via the pigment layers irregularly disposed on the external surface of the wood or charcoals with intervals. Thus, the shape and brightness of the charcoal flame are constant and do not change. Thereby, the external shape of the charcoal flame is monotonous and the visual effect of the charcoal flame is affected. In addition, the brightness of charcoal flame does not change while the electric fireplace is in use and the intermittent light and shad of the sparkling light-spots is lacking, so the reality and the simulation effect of the charcoal is seriously affected. Furthermore, the structure of most exiting charcoal beds are long strip, the depth from the front to the back of electric fireplace is small, which brings poor three-dimensional effect of the simulative flame and affects the reality of charcoal flame structure.

SUMMARY OF THE INVENTION

To solve the problems such as dull appearance, bad three dimension, poor visual effect and etc . . . The present invention provides a stereo flexible charcoal bed used on an electric fireplace. The main object of the present invention is to provide a stereo flexible charcoal bed with varying charcoal flame structure, intermittent light and shad of the sparkling light-spots, good sense of stereo and perfect visual effect.

Another object of the present invention is to provide a electric fireplace with stereo charcoal bed, the light-spots of which is sparkling and intermittent light and shad, and the reality and visual effect of which is perfect. The problems of the existing technology such as bad simulation effect, lack of the sense of stereo and reality are solved.

According to one exemplary embodiment, the present invention relates to a stereo flexible charcoal bed comprising a vessel with at least one transparent bottom, a number of charcoals disposed in the vessel comprising a number of movable light-holding charcoals with a plurality of transparent surfaces, an imaging mechanism disposed on the charcoals. The charcoal bed is a kind of structure of vessel, and a number of light-holding charcoals with a plurality of transparent surfaces are disposed in the vessel, which replaces the wood or charcoal bed with integral structure of the conventional electric fireplace. Because of the relative positioning function of the vessel, the light-holding charcoals of various sizes and shapes in the vessel can change the stacking position in the vessel arbitrarily to form a charcoal bed structure of various shapes. Users can customize the figure of the charcoal bed according to personal visual preference to satisfy every kind of visual requirements. At the same time, the visual effect of the electric fireplace is improved. The transparent surface on the light-holding charcoal refers to a certain surface of the light-holding charcoal, which is photic, then refracts and reflects the light passing through, and simultaneously, reflects external light, so the light is refracted and reflected inside the light-holding charcoal, among the light-holding charcoal, as well as between the light-holding charcoal and the image screen for several times, and a light-holding effect is achieved. In addition, the shape and size of the light-holding charcoal, the number and transparent property of transparent surfaces can be chosen according to personal preference. A plurality of light-tight surfaces could be disposed on the light-holding charcoals as well. The imaging mechanism is disposed on the charcoals. The light projected by the light source disposed on the electric fireplace and the flame generator passes through the transparent bottom of the vessel and then projects to the charcoals disposed in the vessel. An image of burning charcoal flame is formed on the imaging mechanism disposed on the charcoals.

Preferably, the vessel (1) is of oblique structure or a strip-shaped transparent flat box disposed obliquely, a transparent cover is disposed on the vessel, the imaging mechanism is disposed on the cover. The strip-shaped transparent flat box meets the structure requirement of general electric fireplace. Although the vessel could be disposed horizontally, the vessel with oblique structure or disposed obliquely meets the structure characteristics of general charcoal flame which is lower at front and higher at back better. Meanwhile, the vessel is of constant thickness structure, which avoids the regional brightness variation of the imaging screen brought by the variation of the thickness of vessel. Therefore, the vessel with oblique structure or disposed obliquely not only simulates the structure characteristics of charcoal flame which is lower at front and higher at back, but also avoid the regional brightness variation of the imaging screen brought by the variation of the thickness of vessel. The transparent cover disposed on the vessel can guarantee the exterior structure strength of charcoal bed, as well as facilitate the charcoal adjustment in the vessel.

Preferably, the cover is of flat structure, the imaging mechanism is a mat surface structure disposed on the lower side of the cover or a imaging piece attached on the lower side of the cover, the area of the mat structure or the size of the imaging piece matches the area or the size of the cover. The imaging mechanism is disposed on or close to the cover with flat structure. Since the imaging mechanism and the cover are on the same plane, a clear charcoal flame image is achieved and the definition of the charcoal flame is guaranteed. Besides, both the imaging mechanism with mat structure and the image film are existing technology, and others available imaging mechanism structures could also be acceptable.

As a metamorphic exemplary embodiment of the charcoal bed, a number of movable light-holding charcoals with a plurality of transparent surfaces are disposed under the cover. A number of movable light-holding charcoals disposed under the cover increase the three dimension of the charcoal bed figure. Furthermore, the position of charcoals disposed under the cover could be moved arbitrarily. Users can customize the figure of the charcoal bed according to personal visual preference to satisfy the visual requirements of every kind.

Preferably, the light-holding charcoals are a polyhedron with numerous refracting surfaces, a charcoal flame bright section is formed at where the light-holding charcoals are close to the imaging mechanism, a wedge gap around the charcoal flame bright section is a light-holding section. The polyhedron light-holding charcoal with numerous refracting surfaces has the functions of refraction and reflection. Under the projection of irregular light from the electric fireplace flame generator, the refraction effect of the light-holding charcoal makes the light of a certain period and a certain angle focus on the imaging screen. Viewing from the image screen, the surface of the light-holding charcoal disposed close to the imaging screen forms a charcoal flame bright section which is similar to the sparkling light-spots of burning charcoal. The light from the flame generator is intermittent, so the sparkling light-spots are intermittently bright and shade, which is very similar to the burning and lighting circumstance of real charcoal, and with strong reality. Besides, some varying light feels like being held in the charcoal bed after numbers of refraction and reflection by the light-holding charcoal, and some varying light project directly onto the image screen, some light reflect several times by the surface of the light-holding charcoal, that is to say numerous reflections in the wedge gap, and superposition of several lights, together with the remained visual and the image combination function of individual brain, the a light-holding section is formed in the wedge gap around the charcoal flame bright section which makes people feel like that the flame stays near the gap space of the charcoals and burns with a rolling and phantasmagoric configuration, further improves the reality of the charcoal bed and the visual aesthetic feeling of the electric fireplace. The light-holding charcoals can also be of a translucent structure. As the transparent effect of the translucent structure is relatively worse, the light transmittance of the charcoal bed is lower, and the brightness of sparkling light-spots and the light-holding section is of lower. However, the simulative charcoal flame of the charcoal bed has a haze feeling and thus another kind of prospect.

Preferably, a plurality of simulative charcoals with nature charcoal shape are disposed in the vessel, the simulative charcoals are of transparent or translucent, the proportion of the simulative charcoals and the light-holding charcoals is from 1:2 to 1:8. By interlarding optimum amount of simulative charcoals with transparent or translucent structure in the light-holding charcoals, the charcoal bed structure is more close to the real charcoal flame. What need to be illustrated is that the shape of the charcoal could be of nubbly structure or stick or stick structure with branch. As to the simulative charcoals with transparent and translucent structure, the simulative charcoal with translucent structure is preferred because the relatively weak light transmit capability of the simulative charcoal with translucent structure makes the imaging screen looks darker thereon and some charcoals among the charcoal bed appears to be of burning less intensely. At the same time, the brightness of the outline of simulative charcoals with translucent structure under the projection of the light from the electric fireplace flame generator and the refracting and reflecting light from the light-holding charcoal with polyhedron structure is obviously greater than the brightness of the central portion of charcoals, which accords with the structure characteristics of charcoals at early stage of burning, and thus the simulation effect of the charcoal is obviously enhanced.

According to another exemplary embodiment, the present invention relates to a electric fireplace with stereo flexible charcoal bed, comprising a light source, a flame generator, an imaging screen and a stereo flexible charcoal bed disposed at the bottom of the imaging screen comprising a vessel with at least one transparent bottom, a number of charcoals disposed in the vessel comprising a number of movable light-holding charcoals with a plurality of transparent surfaces, an imaging mechanism disposed on the charcoals; and a bottom flame generator disposed at the bottom portion of the vessel. The stereo flexible charcoal bed disposed at the bottom of the image screen of electric fireplace, replaces the traditional fixed charcoal bed with long strip shape. Since the charcoals are disposed inside the vessel, charcoals of various sizes and shapes could be stacked in the vessel with arbitrarily position to form a charcoal bed structure of various shapes. Users can customize the structure of charcoal bed according to personal visual preference to satisfy different kinds of visual requirement, and the visual effect of the electric fireplace is improved. Considering that the light from flame generator disposed at the back of the image screen is hard to project to the charcoals disposed in the front of electric fireplace, a flame generator is specifically disposed at the bottom of vessel, in this way, light can pass the transparent vessel bottom to illuminate the charcoals and simulate intermittent light and shad of the sparkling light-spots on the imaging mechanism disposed above the charcoals. Compared with the traditional electric fireplaces, the charcoal flame has strong sense of stereo and reality.

Preferably, the vessel (1) is of oblique structure or a strip-shaped transparent flat box disposed obliquely, the vessel is disposed at front side of the imaging screen; the length of the vessel is equal to the width of the imaging screen. The strip-shaped transparent flat box meets the structure requirement of general electric fireplace. Although the vessel is disposed horizontally, the vessel with oblique structure or disposed obliquely meets the structure characteristics of general charcoal flame which is lower at front and higher at back better. Meanwhile, the vessel is of constant thickness structure, which avoids the regional brightness variation of the imaging screen brought by the variation of the thickness of vessel. Therefore, the vessel with oblique structure or disposed obliquely not only simulates the structure characteristics of charcoal flame which is lower at front and higher at back, but also avoid the regional brightness variation of the imaging screen brought by the variation of the thickness of vessel. The transparent cover disposed on the vessel can guarantee the exterior structure strength of charcoal bed, as well as facilitate the charcoal adjustment in the vessel. Just like the length of the conventional charcoal bed is same with the width of the image screen, the length of the vessel is same with the width of image width of electric fireplace too.

Preferably, a transparent cover is disposed on the vessel, the imaging mechanism is a mat surface structure or a imaging piece attached the charcoals, the area of the mat structure or the size of the imaging piece matches the area or the size of the cover. The imaging mechanism is disposed on or close to the cover with flat structure. Since the imaging mechanism and the cover are on the same plane, a clear charcoal flame image is achieved and the definition of the charcoal flame is guaranteed.

Preferably, a plurality of simulative charcoals with nature charcoal shape are disposed in the vessel, the simulative charcoals are of transparent or translucent, the proportion of the simulative charcoals and the light-holding charcoals is from 1:2 to 1:8. By interlarding optimum amount of simulative charcoals with transparent or translucent structure in the light-holding charcoals, the charcoal bed structure is more close to the real charcoal flame. As to the simulative charcoals with transparent and translucent structure, the simulative charcoal with translucent structure is preferred because the relatively weak light transmit capability of the simulative charcoal with translucent structure makes the imaging screen looks darker thereon and some charcoals among the charcoal bed appears to be of burning less intensely. At the same time, the brightness of the outline of simulative charcoals with translucent structure under the projection of the light from the electric fireplace flame generator and the refracting and reflecting light from the light-holding charcoal with polyhedron structure is obviously greater than the brightness of the central portion of charcoals, which accords with the structure characteristics of charcoals at early stage of burning, and thus the simulation effect of the charcoal is obviously enhanced.

The essential effect of the present invention is to solve the monotone charcoal flame, bad sense of stereo and poor visual effect of the exiting electric fireplace, meanwhile, the problems such as bad simulative effect, and lack of reality and the sense of stereo are solved as well. The charcoal flame structure of the present invention could change arbitrarily and the light-spots of burning flame are sparkling intermittently with bright and shade. The visual effect and the authenticity are both perfect.

Preferred Embodiment 2

As shown in FIG. 3, the vessel 1 is a obliquely disposed strip-shaped transparent flat box with uniform thickness. A number of charcoals are disposed in the vessel 1, the charcoals comprises a number of movable light-holding charcoals 2 with a plurality of transparent surfaces and a plurality of simulative charcoals 4 with nature charcoal shape. The proportion of the simulative charcoals 4 and the light-holding charcoals 2 is 1:8. A transparent cover 7 is disposed on the vessel 1, the cover 7 is of flat structure, the imaging mechanism 3 is a imaging piece attached on the lower side of the cover 7, the size of the imaging piece matches the size of the cover 7, a number of movable light-holding charcoals 2 with a plurality of transparent surfaces and a plurality of simulative charcoals 4 with nature charcoal shape are disposed under a partial section of the cover 7, the proportion of the simulative charcoals 4 and the light-holding charcoals 2 is 1:5. The other structures of the flame curtain are the same as that described in the first preferred embodiment.

Preferred Embodiment 3

As shown in FIG. 4, a electric fireplace with stereo flexible charcoal bed comprises a light source, a flame generator 9 and an imaging screen 10. A stereo flexible charcoal bed disposed at the front bottom of the imaging screen, comprises a vessel 1, the vessel 1 is a strip-shaped transparent flat box with oblique structure, the length of the vessel 1 is same with the width of the image screen; a number of charcoals disposed in the vessel 1 comprising a number of movable light-holding charcoals 2 with a plurality of transparent surfaces and a plurality of simulative charcoals 4 with nature charcoal shape, the simulative charcoals 4 are of translucent structure, the proportion of the simulative charcoals 4 and the light-holding charcoals 2 is 1:2. A red transparent cover 7 is disposed on the vessel 1, the imaging mechanism 3 is a mat surface structure disposed on the lower side of the cover 7. The mat structure is attached on the lower side of the cover. A bottom flame generator 8 is disposed below the vessel 1.

When the electric fireplace with a flame curtain is in use, the flame simulation process of the electric fireplace image screen is the same with the conventional electric fireplace. When the light of the light source disposed at the bottom of the electric fireplace and the bottom flame generator is project to the light-holding charcoals in the vessel, light at a certain period and with a certain angle focuses on the image screen. Viewing on the image screen, a charcoal bright section is formed where the light-holding charcoals are close to the imaging mechanism, which is very familiar to sparkling light-sports of burning charcoals. Because the light from the bottom flame generator is pulsatile and intermittent, the sparkling light-spots or the burning section are intermittently bright and shade, which is very similar to burning and lighting circumstance of real charcoal. Besides, some varying light feels like being held in the charcoal bed after numbers of refraction and reflection by the light-holding charcoal. A light-holding section is formed in the wedge gap around the charcoal flame bright section which makes people feel like that the flame stays near the gap space of the charcoals and burns with a rolling and phantasmagoric configuration, further improves the reality of the charcoal bed and the visual aesthetic feeling of the electric fireplace (as shown in FIG. 5). As to the charcoals with translucent structure disposed in the vessel, they are less pervious to light and thus look darker on the image screen, and thereby some charcoals with less burning level appear in the charcoal bed. Under the projection of the light from the electric fireplace flame generator and the refracting and reflecting light from the light-holding charcoals, the brightness at the outline of the charcoal is greater than the brightness at the center of the charcoal. Such structure conforms to the structure characteristics when charcoals or wood start burning, and thus the simulation effect of the charcoal is obviously improved. The structure that the charcoal bed with plane shape is disposed in front of the image screen strengthens the bottom structure of charcoal flame. The flame structure is more three-dimensional, and the sense of stereo of the charcoal flame is improved a lot. The transition of charcoals disposed upper and lower is nature and feels like the nature configuration of charcoal flame.

When the shape of charcoal bed needs to be change, the only thing one need to do is to open the cover plate of the vessel and stir, add or remove the charcoals disposed in, or change the proportion of various charcoals to reshape the shape of the charcoal bed. Not only the shapes of charcoals bed is changed, the light path of refraction and reflection inside the charcoal bed the flame bright section and the light-holding section also changes. Therefore, a brand new appearance presents leads to a completely different visual effect.
